Boat on the reservoir
Park Highlight
Explore Eleven Mile Reservoir
The park's main attraction is the 3,405 surface-acre reservoir. The reservoir's boaters are challenged by the tricky winds and fast-rising storms that occasionally sweep the area. Anglers consistently tout Eleven Mile’s large reservoir for its outstanding fishing. When not reeling in a trophy fish, there are nearly five miles of scenic hiking and biking trails that await exploration. Canoe the day away around the shores of the backcountry and camp comfortably in one of our campsites.
Body water-contact activities including scuba diving, water skiing, jet skiing, wading (without waders), swimming, etc. are prohibited.

Boating and Fishing
Boating
All types of boating are popular on this large reservoir, including: kayaking, canoeing, sailing and motorboating. Islands within the reservoir are closed to all public use.
Inspections
A boat inspection is required on all trailered vessels that are intending to either be launched on or removed from either reservoir. Any boat that is found to be contaminated before entering the water will be refused admittance to the reservoir until it is satisfactorily decontaminated. Boats found to be contaminated after leaving the water will be assisted by Parks and Wildlife staff in ensuring that the boat is clean prior to exiting the boat ramp parking lot.
Weather
Sudden storms with strong winds and high waves can develop quickly at Eleven Mile. If you see storm clouds building on the horizon, please exercise caution by heading closer toward shore. Underwater hazards are frequently found in the reservoir and not all are marked. Boaters should be especially careful when within 150 feet of any shoreline.
Fishing
Fish for brown, cutthroat, cutbow and rainbow trout, as well as northern pike. The lake is one of very few in Colorado stocked with Kokanee salmon, but snagging for Kokanee salmon is prohibited. Carp abound in the shallow bays and inlets, providing great bow fishing.
Gold Metal Water fishing opportunities exist on the South Platte River within Eleven Mile State Park by the inlet.
Fishing Rules
- All fishing is flies and lures only and is catch and release within 100 feet of the mouth of the inlet.
- The use of live minnows is strictly prohibited.
- All fishing is prohibited from the restricted area near the dam on the east end of the reservoir. This area is marked by a closure buoy line that stretches across the lake at that point.
- Fishing is also prohibited on islands and docks.
Fish Species and Bag Limits
See the Fishing Atlas for fishable species at this location and the Fishing Brochure (PDF) for daily bag limits.

Learn more about aquatic nuisance species, as well as clean, drain, dry and decontaminations.
Contaminated Vessels
Any boat found to be contaminated will be refused admittance to the reservoir until decontaminated. After inspection, if a decontamination is needed the ANS Inspector will direct the boater where to go during the hours of 7 a.m. to 5 p.m.
Inspection Hours
Mandatory boat inspections begin April 15. Inspections are available from a half hour before sunrise to a half hour after sunset during regular boating season.
Mandatory Inspections and SealsNew Zealand Mudsnail and Eurasian Watermilfoil
New Zealand mudsnails negatively affect aquatic insect larvae, native snails, as well as fish populations. Eurasian watermilfoil is an aquatic noxious weed that forms dense mats which restrict fishing and boating. The mats shade and choke out native aquatic plants, foul beaches and decrease oxygen levels in the water, destroying habitat and food needed by fish and birds.
